VMWorld 2009 Session Notes: vCenter AppSpeed

1 09 2009

vCenter AppSpeed
1. Monitors apps performance based on inspecting traffic on the vswitch.
2. You must be able to measure end user performance to troubleshoot it.
3. Appspeed let’s you monitor as you virtualize (assured migration).
4. Appspeed server discovers, maps and monitors performance vs SLA’s. It puts a small vm on each host.
5. Environment map automatically created. Shows interdependencies. This gives you a deeper understanding of how everything is connected.
6. AppSpeed then monitors performance letting you drill down and identify bottlenecks. Alerts automatically. You can trend over time.
7. AppSpeed can then analyze root causes.


Notes from the vSphere upgrade

1 06 2009

Here are a few tips from my experience with doing an in-place upgrade to vSphere….

1. If you are running vCenter and Update Manager in vms, make sure to move those vms off the host MANUALLY before trying to upgrade the host to vSphere.

2. When upgrading tools and hardware, and you have vCenter and update manager in vms, upgrade vCenter and Update Manager FIRST. This will make update manager and vcenter ready to use baselines and remediation to upgrade tools and hardware on other guests.

3. Use the vi client and login to the actual host that is running the vCenter and update manager vms, when upgrading tools and hardware on vCenter and update manager. Once they are upgraded, you can then log back in to your vCenter server like normal to do the other upgrades.

4. It may take an extra reboot of your vCenter of Update Manager vms for them to reliably see eachother after a tools/hardware upgrade.
